Greg Jamison’s bid to buy the Phoenix Coyotes and keep the team in Glendale faces yet another deadline Friday along with renewed concerns over whether his ownership group has the investors and money to buy the team from the National Hockey League.

NHL deputy commissioner Bill Daly says the league isn’t worried about the state of Jamison’s bid.

Daly also dismissed speculation this week that Jamison now doesn’t have the money or financing to buy the team or that the NHL was looking at cutting the sale price or some kind of special financing to get the deal done.

But confidence in the deal is waning, even among some Coyotes boosters.

Several sources in Arizona familiar with the Coyotes machinations and supportive of Jamison’s bid are asking with concern why a deal hasn’t been finalized, where Jamison’s money is coming from and who his partners are.

Hanging over all of this is the fact that the $300 million Coyotes-friendly arena deal approved by the city of Glendale can’t be signed by Jamison until he buys the team.

Free agent Coyotes captain Shane Doan has given Jamison until Friday to show some significant progress or finality in buying the league-owned franchise. Otherwise, Doan will sign with another team as soon as next week, according to his agent Terry Bross. Doan has been waiting for the Coyotes’ three-year ownership saga to resolve itself.

Bross said Doan doesn’t want to disclose his short list of teams outside of Phoenix. There is interest from Montreal, Detroit, Pittsburgh, Philadelphia and the New York Rangers.

Doan is scheduled to meet with the Montreal Canadians next week.

Jamison has been trying to buy the Coyotes since last year with a purchase of the team previously promised by December 2011, February and March of this year, and then after the NHL season and the Glendale arena vote and legal fights. The deadline has continually been pushed back.

Doan has extended his own Coyotes deadline several times waiting for a deal close.

The NHL has owned the Coyotes since 2009 when it bought the team out of Chapter 11 bankruptcy for $140 million. It wants to sell the Coyotes to Jamison for $170 million.

Jamison would keep the team playing in Glendale and end three years of uncertainty that the hockey franchise could move to another market.

Those backing the Jamison bid in Arizona and hockey circles have previously said he has put together the money to buy the team. They also promised the odds of that happening soon were improved with Glendale’s approval of a $300 million, 20-year arena management deal that helps Jamison’s bid.

The city has a court hearing next week with backers of sales tax repeal who wanted to get a ballot measure to city voters. The city disqualified the sales tax repeal from the ballot. The tax increase will help pay Glendale’s arena payments to Jamison if he buys the Coyotes.

Glendale has disqualified two ballot measures in opposition to that bid, including one that asked voters to void the arena deal.

But that city arena deal with Jamison is not yet signed, and won’t be until he is able to buy the team. Glendale city spokesman Julie Frisoni confirms the arena contract and management deal is not yet signed by Jamison’s group.

Jamison’s camp and the NHL discounted rumors yesterday that his ownership bid has lost a smaller investor and was short of the money needed to buy the team even after the Glendale subsidy and disqualification of the ballot measures.

Jamison has not yet disclosed who his financial partners are or how he is coming up with the money. Jamison is the former CEO of the San Jose Sharks and he quietly became co-owner of a minor league hockey team, the Bay Area Seals, in June.

The sports executive has experience managing and running arenas, but he needs investment money to buy the team. That has proven complicated with Jamison relying on multiple investors, and perhaps financing avenues, to try to close the deal.

That includes some international and Middle Eastern money. There have been discussions with a Saudi investment group about a stake in the Coyotes.

The continued delays with the Jamison purchase increase the odds of the NHL running the team one more year in Glendale.

Daly wouldn’t say if that was an option this year, but the NHL season starts in October and team travel plans are well under way.

A new Glendale mayor and city council will be elected this year and in office in January.

That new group of Glendale lawmakers is almost certain to be less pro-Coyotes than the current City Council.

The current Glendale council approved the $300 million deal with Jamison, and has agreed to pay the NHL $50 million to run the arena for the past two seasons.

A new council could try to undo the $300 million deal if Jamison hasn’t signed the contract and bought the Coyotes.

Ken Jones, one of the petition gatherers for the failed anti-arena deal measure, said he wants to also push high surcharges on hockey games at the arena to offset the costs of the city arena deal.
